Abstract: 1,052,549. Sailing boat. D. DE MONFREID. March 16, 1965 [March 27, 1964], No. 11178/65. Heading B7V. In a sailing boat 1, Fig. 1 (not shown), the rigging consists of a single sail 2, of the lateen or Arab type and essentially comprises a slanting sail-yard or lateen-yard 3 provided at the lower end with a rearwardly elbowed extension 4 the after end of which is secured to the deck of the boat by means of a Cardan type joint 5, an intermediate point of the sail-yard fitted with a swivel-pin 51 being continuously maintained in the fore-and-aft vertical mid-plane of the boat by two retaining guys 53, 54. The swivelpin 51 supports a yoke to which the upper ends of retaining guys 53, 54 are attached. The lower ends of the guys are attached at 55, 56 to the two sides of the hull on an axis which passes athwartships through the centre of joint 5. Stays 71, 71a join the yoke to points 73, 73a of the hull which are located aft of the joint 5 and retaining tackle 81, 82, 83 secured to the hull is attached to winch 84. The sail-yard is therefore restrained from movement about the horizontal axis of joint 5. The axis of the swivel-pin 51 substantially passes through the centre of the joint and thus constitutes a fictitious mast whose forward inclination is limited by stays 71, 71a and the orientation of the sail-yard about this fictitious mast is controlled by winch 84 and retaining tackle 81, 82, 83. Clew line 87 which passes over a stern pulley 88 to be retained by cleat 89 is attached to the aftermost corner of the sail 2 and controls the extent to which the sail may be permitted to belly. The lower portion of the yard 3 and elbowed extension 4 are reinforced by a right-angle brace 13 of sheet steel, Figs. 7 and 8 (not shown).

Patent GB-1073074-A (GB)
Abstract: 1,073,074. Interconnection system. STANDARD TELEPHONES & CABLES Ltd. Sept. 4, 1964 [Sept. 6, 1963], No. 36337/64. Heading H4K. In a communication, system of parallel connected stations having talk/receive keys where a calling signal from one station is broadcast to the others, the response by the called station automatically blocks the remaining stations from receiving further communication. Fig. 1 shows one of the stations which are all parallel connected to a central amplifier over terminals 1 to 10. Actuation of an engage key Se1, Se2 (shown at rest in Fig. 1) in one station energizes the amplifier and by talk key (S1, S2) a calling signal can be broadcast to the stations, all of which are open to receive signals in the rest position: the called station responds by pressing its own engage key (Sel, Se2). With two Se2 switches engaged two parallel connected resistors R1 are in series with relay H, which provides sufficient voltage to energize it. Relay P and its contacts P1, P2, P3 operate and actuate the blocking relay B in only those stations which have not responded with the engage key (S1, S2) i.e. not a party to the conversation. The action of relay 3 is to remove the microphone/loud-speaker SW from the circuit by contacts b2, b3 and to light a warning lamp LAb by b1. In the communicating stations, however, resistance R2 has not been shorted out by Se2 so the blocking relay is inoperative and lamp LAs is alight instead. To call a conference, key k is provided to apply equal potentials to either side of relay H so nullifying the setting up of the blocking action until all the required parties have responded, release of k allows the remaining; stations to become blocked. Fig. 3 shows relays Ga, Gb, Gc used to broadcast within a certain group of stations only, the link between terminals 9<SP>1</SP> + 6<SP>1</SP> being removed. Depression of key k actuates the chosen relay Gc and by the opening of its switch Gc2 prevents the blocking action from being applied to stations in this group; the engage key Sel, Se2 then being used, as before, to start the call. Some of the stations in the system may have the lead 5 removed so that they can only receive and not initiate a call.

Abstract: 1,230,564. Control of A.C. motors. ROLLSROYCE Ltd. 16 May, 1968 [19 May, 1967], No. 23372/67. Heading H2J. A two-phase induction motor 10 is supplied from an oscillator 11 which is connected to reference winding 13 through phase-shifter 16, and is connected to control winding 15 through unit 18 receiving direction and speed control signals 19, 20. A wave-squaring and frequencydoubling unit 17 produces an operating signal 21 for the unit 18 and a register 22. The latter comprises a number of flip-flops 25 receiving digits on data lines 27 from a computer 26 which is adapted to generate binary control numbers each defining a speed at which the motor is to operate. The control number is loaded into the computer by successive starting signals at predetermined intervals 28, the register being counted down by one digit per pulse of current supplied to the motor so that, when the register is at zero, the supply to the motor is stopped. If the control number is less than that corresponding to maximum speed, the motor is disconnected, after receiving a number of pulses, until the next starting signal occurs. The signal on each data line 27 is introduced to its associated flip-flop 25 through AND- gates 29, 30 which are enabled by the signal 28. This signal is further applied through a monostable device 31 whose output signal 28A is connected to the flip-flops for transferring the input signals to the outputs. The signal 28A is also connected through an inverter to the flip-flops which are thereby cleared at the beginning of the delay period of the monostable device. The outputs of the flip-flops 25 are connected through an OR-gate 32 and AND-gate 33 to provide the signal 20. The gate 33 has an input from flip-flop 34 so that a partial pulse is not included in the count-down of the register 22. The count-down commences when the signal 20 is connected to the first flip-flop 25 defining the least significant digit of the control number. The connection is made through OR-gate 36. The flip-flops 25 are interconnected through OR- gates 37 whereby a transition of the signal 20 reverses the output of the first flip-flop followed by similar action of the next flip-flop until the register is counted down to zero. The direction control signal 19 is connected to a flip-flop 40 associated with AND-gates 41, 42, which are enabled by the signal 20. A supply transformer 47 is connected to semi-conductor switches 45, 46, for energizing the motor reversibly. The motor may drive a fuel control valve for a gas turbine engine, the computer receiving a feedback signal representing the position of the valve which is set in accordance with a control number. The computer may also receive a feedback signal signifying the speed of the engine, Fig. 3 (not shown).

Abstract: 1,230,899. Injection moulding pipes. ENGLEFIELD PLASTIC INDUSTRIES Ltd. 22 Dec., 1969 [20 Dec., 1968], No. 62323/69. Heading B5A. A tube of J shape is injection moulded in a mould cavity formed between a two-part die and a core comprised of four separable parts 26-29, the parts 28, 29 having a dovetail type sliding connection with the part 27 secured to the part 26 by a bolt 35. The core is placed in a cavity 11 in the lower half 7 of a die, and a flange 31 of the core is located between the end of the cavity and a block 17 shaped to receive one end of the part 26. When a similar upper die half is joined to the lower half, one end of the mould cavity is closed by the flange 31, and the other end closed by the end 51 of a crosshead 48 reciprocable on guides 50 between the die halves and driven by a double-acting pneumatic ram 45. The end 51 is recessed to enclose the shaped ends of the core parts 27 and 29. Plastics material, e.g. cross-linked polyethylene is injected through passage 24, and when the tube has hardened the cross-head 48 is retracted, the die opened, and the tube and core removed. Compressed air is delivered through a bore 43 to force the parts 29, 28 to slide on the part 27 and project, in turn, from the free end of the bend of the tube, whereupon they are removed manually. The part 27 is then unbolted and removed from the tube, after which the said free end is plugged and compressed air forced therethrough into the tube to urge the part 26 outwardly from the tube to be finally removed manually.

Abstract: 1,238,375. Signal processing. SOC. NATIONALE DES PETROLES D'AQUITAINE. 17 July, 1968 [20 July, 1967], No. 34094/68. Heading H4D. [Also in Division G2] The propagation time of a signal through a system is obtained by transmitting a linearly frequency-modulated signal through the system, recording the system output in the form of a pattern on a photosensitive support, using the pattern as a diffraction element for coherent light, and imaging the diffracted light by means of a cylindrical lens, propagation time being represented by spatial separation of points in the image. As applied to seismic exploration the transmitted frequency sweep is preferably symmetrical with respect to time, and the reply signals picked up by detectors at and remote from the transmission point are recorded, e.g. magnetically. The recorded signals are converted to variable density or variable width traces 14a, 14b &c. (Fig. 4) on film 13, which is illuminated by collimated laser light. Cylindrical lens 15 focuses the zero order or either of the first order diffraction patterns in plane 17. In an alternative arrangement (Fig. 7) the traces are recorded on a motor-driven spooled film 21 (or on a photosensitive loop, provided with recording and erasing devices) and are illuminated by collimated laser light. Photodetectors 24 (one per trace) detect the diffraction pattern and their output is applied to chart recorder 26. Between film 21 and cylindrical lens 23 is a stop whose aperture is related to the duration of the transmitted acoustic signal and to the speed at which film 21 is driven.
